Description

Technical Field

[0001] This utility model relates to the field of sewing machine technology, and in particular to a power supply mechanism for a sewing machine. Background Technology

[0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on fabric, so that one or more layers of fabric are interwoven or sewn together. When a sewing machine is in use, its power supply structure can provide the necessary power to ensure that the sewing machine continues to operate normally.

[0003] Utility model patent CN205725487U discloses a power supply circuit for an electric sewing machine, comprising: a rectifier circuit having an input terminal and an output terminal, the input terminal being coupled to an external AC power supply and the output terminal outputting DC power; and a switching power supply circuit having an input terminal and an output terminal, the input terminal being coupled to the output terminal of the rectifier circuit to modulate the DC power output from the rectifier circuit and output a low-voltage power supply. This utility model's electric sewing machine power supply circuit effectively converts external AC AC power into DC power through the rectifier circuit, and effectively steps down the DC power before outputting it to power the various chips within the driver through the switching power supply circuit.

[0004] Existing power supply circuits for electric sewing machines have the following drawbacks: they lack a structure to reinforce the power cord, and unstable power cords can affect the smoothness of the sewing machine's operation. Therefore, we propose a new power supply mechanism for sewing machines. Summary of the Invention

[0005] The main objective of this invention is to provide a power supply mechanism for a sewing machine, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A sewing machine power supply mechanism includes a base, a sewing machine body on the top of the base, a motor housing on one side of the sewing machine body, and a power supply component located inside the base on one side of the sewing machine body. The power supply component consists of a first cable fixing sleeve and a second cable fixing sleeve. The second cable fixing sleeve is embedded inside the first cable fixing sleeve. The second cable fixing sleeve has a through hole through which a first power line and a second power line are arranged. The second cable fixing sleeve also includes a sealing gasket.

[0008] Furthermore, the sealing gasket is located between the first power line and the second power line and the second cable fixing sleeve, and the first power line and the second power line are electrically connected.

[0009] Furthermore, the motor housing is equipped with a drive motor, and the current output terminal of the second power supply line is electrically connected to the current input terminal of the drive motor.

[0010] Furthermore, the sealing gasket is made of styrene-butadiene rubber.

[0011] Furthermore, a nameplate is mounted on one side of the base by screws.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By using the No. 1 power cord, the No. 1 cable fixing sleeve, the No. 2 cable fixing sleeve, the No. 2 power cord, and the sealing gasket, the No. 1 cable fixing sleeve not only effectively protects the signal transmission quality of the No. 1 and No. 2 power cords, but also protects them from impacts. The No. 2 cable fixing sleeve and the sealing gasket work together to further enhance the stability of the No. 1 and No. 2 power cords in the sewing machine body. By reinforcing the No. 1 and No. 2 power cords in the sewing machine body, the stability of the sewing machine body during operation can be effectively enhanced. Attached Figure Description

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figure 1-3As shown, a sewing machine power supply mechanism includes a base 1, a sewing machine body 2 is mounted on the top of the base 1, a motor housing 3 is mounted on one side of the sewing machine body 2, and a power supply component 4 is provided inside the base 1 and on one side of the sewing machine body 2. The power supply component 4 consists of a first cable fixing sleeve 402 and a second cable fixing sleeve 403. The second cable fixing sleeve 403 is embedded inside the first cable fixing sleeve 402. The second cable fixing sleeve 403 has a first power line 401 and a second power line 404 provided inside through a through hole. The second cable fixing sleeve 403 also includes a sealing gasket 405.

[0020] The sealing gasket 405 is located between the first power line 401 and the second power line 404 and the second cable fixing sleeve 403, and the first power line 401 and the second power line 404 are electrically connected.

[0021] In this embodiment, as shown Figure 3 As shown, the sealing gasket 405 can fit tightly with power line 401 and power line 404, enhancing the stability of power line 401 and power line 404.

[0022] The motor housing 3 is equipped with a drive motor 6, and the current output terminal of the second power line 404 is electrically connected to the current input terminal of the drive motor 6.

[0023] In this embodiment, as shown Figure 2 As shown, power line 404 can supply power to drive motor 6.

[0024] The sealing gasket 405 is made of styrene-butadiene rubber.

[0025] A nameplate 5 is mounted on one side of the base 1 by screws.

[0026] In this embodiment, as shown Figure 1 As shown, nameplate 5 can easily display information such as the sewing machine's production date and operating power.

[0027] It should be noted that this utility model is a power supply mechanism for a sewing machine. During operation, it utilizes a primary power cable 401, a primary cable fixing sleeve 402, a secondary cable fixing sleeve 403, a secondary power cable 404, and a sealing washer 405. The primary cable fixing sleeve 402 is made of copper, possessing excellent conductivity and mechanical strength. It effectively protects the signal transmission quality of the primary and secondary power cables 401 and 404, and also provides impact protection for them. Furthermore, the secondary cable fixing sleeve... 403 is made of polyurethane foam rubber material, which is relatively soft. At the same time, the sealing gasket 405, made of styrene-butadiene rubber material, is also soft and can fit tightly with the No. 1 power cord 401 and the No. 2 power cord 404. Through the cooperation of the No. 2 cable fixing sleeve 403 and the sealing gasket 405, the stability of the No. 1 power cord 401 and the No. 2 power cord 404 in the sewing machine body 2 can be further enhanced. By reinforcing the No. 1 power cord 401 and the No. 2 power cord 404 in the sewing machine body 2, the stability of the sewing machine body 2 during operation can be effectively enhanced.
